I SPECIFICATION forming part of Letters Patent No. 742,232 dated October27, 1903.

Application filed March 21, 1900.. Serial No. 9,491. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. READ, a citizen of the UnitedStates,residin g at New York, county of New York, and State of New York,have invented certain new and useful Improvements in Printing-Machines,fully described and represented in the following specification and theaccompanying drawings, forming a part of the same.

This invention relates to certain improvements in printing-machines.

One of the objects of this invention is to produce a simple compactflat-bed printingmachine which is capacitated to either perfect a'web orprint the same in colors, as may be desired.

Another object of the invention is-to produce a flat-bedprinting-machine which is capacitated to print and perfect a pluralityof webs, said webs being associated and delivered as a single product,or to print a single web in a plurality of colors on each side, or toprint and perfect two single webs, said webs being deliveredindependently:

A further object of the invention is to produce a compact, efficient,and cheap web-controlling device which renders unnecessary the loopingmechanisms heretofore used .in this style of printing-machines.

Afurther object of the invention is to produce a compact and efficientmeans for reciprocating the cylinder of a flat-bed travelingcylinderprinting-machine.

With these and other objects in view the invention consists in certainconstructions and in certain parts, improvements, and combinations, aswill be hereinafter fully described and then specifically pointed out inthe claims hereunto appended.

In the accompanying drawings, which form a part of this specification,and in which like characters of reference indicate the same parts,Figure 1 is a side elevation of a printing-machine constructed inaccordance with the invention. Fig. 2 is a plan view of the constructionshownin Fig. 1. Fig. 3 is an end view of the construction shown in Fig.1 look- Fig.

4 is a plan view of another form of printingmachine embodying theinvention, the view being ona smaller scale. Fig. 5 is a side view ofthe printing-machine shown in Fig. 4. Fig. 6 is an enlarged sectionaldetail view of the web -control'ling mechanism preferably employed. Fig.7 is a plan view of the construction shown in Fig. 6. similar to Fig. 6,but "showing the parts in a different position. Fig. 9 is a planview ofthe construction shown in Fig. 8. Fig. 10 is a view of a modified formof web-transferring mechanism. Fig. 11 is a diagram illustrating themovement of the web through the webtransferring mechanism shown in Fig.10. Fig. 12 is a diagram illustrating the movement of the web throughthe machine shown inFigs. 4 and 5 when the same is arranged to print incolors on each side of the Web.

Referring to the drawings, and more particularly to Fig. 1, whichillustrates one concrete embodiment of the invention, 1 and 2 indicateside frames of the machine, which may be of any usual or desired form.These frames serve to support a bed 3, on which the forms are mounted.In the machine shown the forms are arranged in pairs, one pair of forms4 being located on one side of the bed and another pair of forms 5 beinglocated on the other side of the bed. Cooperating with the forms 44 and5 5 is an impression-cylinder 6, this cylinder being preferably andas'shown a traveling cylinder. This cylinder may be supported andoperated in any suitable manner. In the machineshown the cylinder ismounted on a shaft 7, said shaft being journaied in boxes 8, which aresupported in a pair of side carriages 9 and 10. The carriage 9 moves ona way 11, cast or otherwise formed on or secured to the side frame 1,and the carriage 10 moves on a similar way 12, cast or otherwise formedon or secured to the frame 2. The cylinder may be reciprocated over thebed by any suitable or desired mechanism. Preferably, however, thecarriage 9 is provided with a rack 13, said rack being engaged by a gear14, which is mounted on a shaft 15. This shaft 15 is supported in theconstruction shown in sliding bearings which move in and are supportedin slots 16 in the Fig. 8 is a View side frames 1 and 2.

Similarly the carriage 10 is provided with a rack 17, said rack beingengaged by a gear 18, mounted on the opposite end of the shaft 15. Theshaft 15 is further provided in the construction shown with gears 19 and20, said gears engaging stationary racks 21 and '22, arranged onopposite sides of the machine. The shaft 15 is engaged by two arms 23and 24 011 a yokeconnecting rod 25, said yoke being connected to acrank-stud 26, which is mounted on a gear 27. The gear 27 is mounted ona crankshaft 28, suitably supported in bearings, one of which is locatedin the side frame 2 and the other of which is located in a standard 29,mounted on the frame-bed. The gear 27 is driven from a pinion 30,mounted on a powershaft 31, said shaft finding its hearings in theconstruction shown in the side frame 2 and the standard 29.

The construction justdescribed for driving the cylinder is amodification of the multiplying railroad'gear, the operation of which iswell understood by those skilled in the art.

This construction is particularly adapted for use in flat-bedmachines,because all the parts of the driving mechanism, except thegears which drive the carriages, are located heneat-h the bed andbetween the side frames, while the driving-gears are located close tothe frame. An exceedingly compact and efficient driving mechanism istherefore produced.

In order to insure the rotation of the cylinder and to provide for aneven movement of the cylinder in parallelism with the forms, it ispreferably provided with ordinary reg ister-gears 32 33, one of saidgears being located at each side of the cylinder. The gear 32 engageswith a register-rack 34, secured to the side frame 1, and the gearengages a. similar rack 35, mounted on the side frame 2.

The web is led into the machine from a web-roll, the same beingsupported in suitable bearings 37, formed on brackets 38, extending fromthe side frames 1 and 2. The web will preferably be continuously fedinto the machine and to this end is led between a series offriction-rollers 39 and a cooperating feeding-101140. The roll 40 ismounted on a shaft 41, which extends from side frame to side frame andis preferably journaled in suitable hearings in said frames. Although,however, the shaft 41 extends entirely across the machine, the roll 40extends only part way across, this roll being somewhat longer than thewidth of the web. The roll 40 is preferably a continuously-driven roll,and to this end the shaft.- 41 carries a miter-gear 42, said gearmeshing with a similar gear 43 on an upright shaft 44, supported insuitable journals on the side frame 2. The shaft 44E carries on itslower end a bevel-gear 45, said gear meshing with a similar gear 46,mounted on a short stud 47, suitably supported on the side frame 2. Saidstud 47 carries a pinion 48,

which meshes with a gear 49, which is carried on a shaft 50, said shaftbeing mounted in suitable hearings in the side frames. The shaft 50further carries a miter-gear 51, which meshes with a similar gear 52,said gear 52 being mounted on a way-shaft 53, running longitudinally ofthe machine. This shaft 53 is driven in any suitable manner-as, forinstance, by a miter-gear 54: on the crankshaft, which meshes with asimilar gear 55 on the shaft 53.

While a single roll might be used to cooperate with the roll 40, theconstruction is preferably that which has been before described, inwhich a series of rollers is used. The rollers 39 are mounted on arms50, said arms being carried on a rod 57. The rod 57 is supported inbearings 58, formed on extensions 59 on the side frames. Only one ofthese bearings 58 is shown.

Inasmuch as the web is constantly fed into the machine by the operationof the roll 40 and the rollers 39, and inasmuch as in this class ofmachines the web is stationary during the time the printing operationtakes place, it is obvious that means must be provided for disposing ofthe web which is fed in bythe feeding mechanism during thetime when theprinting is performed. \Vhile any of the looping mechanisms ordinarilyused in this style of machines may be used for this purpose, in thepresent machine the web which is fed in by the feeding mechanism duringthe printing operation is preferably taken care of by means of aweb-controller. The construction of this web-controller may be variedwithin wide limits. Preferably, however, said web-controller includes aplurality of web-guides 6O 61 62, around which the web passes, saidguides being mounted so as to move toward and from a common center.During the time when the printing is taking place the guides are beingmoved away from the center, and consequently they take care of the webwhich is being fed in by the constantly-running feeding mechanism duringthe printing operation. As soon as the printing operation is com pletedthe guides are moved toward their common center, thus operating to giveup web to be drawn through the machine. The guides may be mounted invarious ways, so as to give them a movement toward and from the commoncenter which has just been described. Preferably, however, each of theguides is mounted in a pair of arms, said arms being connected to crankson a shaft, whereby they are thrown in and out by the movement of theshaft. In the construction shown the guide is carried by two arms 63,one at each end thereof. Only one of these arms is shown; but theconstruction at each end of the guide is identical. These arms 63 areconnected to and operated by a shaft 64, which extends across themachine from side to side. The arms 63 may be connected to the shaft 64in any suitable or desired manner. In the construction shown, however,the shaft 61 is provided with collars 65, one at each end, from whichextend cars 66, the collars and ears in reality forming cranks. The arms63 are connectedto the ears 66 by means of bolts 67 or in any othersuitable manner. The guide 60 may be connected to the arms 63 in anysuitable or desired manner. In the construction shown, however, pins 68pass through the arms 63, said pins having their ends formed to providecone-bearings, which engage suitable sockets in the guide 60. The pins68 preferably have their ends extended through the arms 63, said endsengaging guides 69, mounted on the side frames of the machine, thefunction of these guides being to cause the guide 60 to move toward andaway from the center in a straight line, orsubstantially so. The collars65 are provided with other sets of cars 70 and 71, and to these cars areconnected arms 72 73, the connection being other suitable manner. Thearms 72 and 73 have pins 76 and 77 extending through them,

said pins being formed to provide cone-bearings in which the guides 61and 62 are supported. The ends of these pins 76 and 77 are extendedthrough the arms and engage guides 78 and 79 on the side frames.

It is obvious that with the construction as described a partial rotationof the shaft 64 will cause the arms to move from the position shown inFig. 8 to the position shown in Fig. 6, and this movement will beeffected during the printing operation, so that the incoming Web will betaken care of by the movement of the guides 60 61 62. When the printingoperation is completed, the movement of the shaft 64: will be reversed,and the guides will thus give up the web to be drawn through themachine.

Any suitable means may be provided for rocking the shaft 64. In theconstruction shown the shaft is provided with a crankarm 80, said armextending outside the frame of the machine. This arm 80 has a rod 81extending therefrom, said rod having a-roller which engages a cam on theshaft 50, before described, the cam being indicated in dotted lines inFig. 1.

The machine is provided with a constant1yrunning feeding-out mechanism,said mechanism being similar in all respects to the feeding-inmechanism, before described. In the construction shown this feeding-outmechanism consists of a roll 82, carried on a shaft 83, extending acrossthe machine from side' machine from side to side.

just described. This mechanism will preferably be a duplicate .of theone described in connection with the constantly-running feeding-inmechanism, and a specific description of it is therefore unnecessary.The operating-guides of this mechanism are marked 89, 90, and 91,respectively, and said guides are operated from a shaft 92. The shaft 92has connected thereto a crank-arm 93, and to this arm is connected a rod94:, which is operated from a cam on the shaft 50, said cam. beingindicated in dotted lines in Fig. 1. In the construction shown the webafter having passed between one set of forms and the travelingimpression-cylinder is transferred laterally and is then led between theother set of forms and the other end of the impression-cylinder. The webmay be transferred laterally by means-of any ofthe ordinary well-knownagencies commonly used in the printing art for this purpose, and the Webmay be either turned over during the operation of transferring it ornot, according as it is desired to perfect it or print it in colors. Twoforms of web-transferrers are shown in the accompanying drawings.

Referring to Fig.2, the transfer of the web is effected by twoangle-bars 96 97, operating in connection with rollers 98 99, the webbeing passed first around the bar 96, then around the bar 97,thenaroundthe roll 98,and then around theroll 99. After receiving its firstimpression the web is led from the couple around a guideroll 95, afterwhich it passes to the angle-bars 96 97, as before described. Afterleaving the roll 99 the web passes around a guide-roll 100 and is againled to the couple, passing between the second set of forms and the otherend of the cylinder. As is usual in such cases, the cylinder-carriagesare provided with guides, one at each end of the cylinder, said guidesoperating to form the loop in which the cylinder travels. In theconstruction shown these guides are marked 101 and 102 and are mountedin cross-bars 103, which are mounted on the carriages 9 and 10,respectively.

The second form of web-transferring device is shown in Fig. 10. In thisconstruction, which is a well-known one, the web after leaving the roll95 passes over a pair of angle-bars 10 105. After leaving the bar 105the web passes over a roll 106, then over a pair of rolls 107, aftervwhich it again goes to the couple. 7

The operation of the machine so far described will be obvious to anyperson familiar with the art to which it belongs. The web passes fromthe web-roll to the constantlyrunning feeding-in rolls 39 and 40 andthenaround the guides 60, 61, and 62 of the webcontroller. After leaving theweb-controller the web passes over a guide 108, then over. the guide101, then between the impression: cylinder and v the forms 4, then overthe guide 102, then over the guide 95, and through the web turning andtransferring mechan- IIO ism, it being supposed in this case that themachine is arranged to perfect. After the web has been transferredlaterally and turned operation.

over by the turning and transferring mechanism it passes over theguide-roll 100, then over the guide 102, then between theimpression-cylinder and the forms 5, then over the guide 101. From theguide 101 it passes overa guide 109, then over a second guide 110, thenaround the guides 91, 90, and 89 of the second web controller, and thento the constantly-running feeding-out mechanism, of which 82 is thedriven roll.

As is well known in this style of machine, the web is stationary betweenthe two webcontrolling mechanisms during the printing As the cylindermoves in one direction on its printing stroke, therefore theweb-controller which operates in connection with the constantly-runningfeeding-in mechanism is operated to give its guides 60, 61, and 62 anoutward radial movement. This movement continues during the printingstroke of the cylinder, and the guides operate, therefore, to take upthe web which is fed into the machine during the printing stroke. Theguides 89, 90, and 91 of the other web controlling mechanism are,however, in their outward position at the time the cylinder begins itsprinting stroke. During the printing stroke, therefore, they are movedinward and give up web to the constantly-running feedingout mechanism.As soon as the printing stroke is completed the guides 60, 61, and 62are moved quickly inward and the guides 89, 90, and 91 are moved quicklyontward. During the time when the cylinder is off impression, therefore,at one end of its stroke the guides 60, 61, and 62, operating inconnection with the constantly-running feeding-in mechanism, operate togive up an amount of web equal to the amount which will be printed onthe next stroke of the cylinder, and the constantly-running feedingoutmechanism operating in connection with the guides 89, 90, and 91 operateto pull through the machine an amount of web equal to that given up bythe guides 60, 61, and 62. When the cylinder reaches the forms and isabout to begin its return stroke, the web-controllers have theiroperation reversed and the web again remains stationary during theprinting operation.

As the web passes from the feeding-out mechanism it may be delivered byany suitableformofdelivery mechanism. Intheconstruction shown thismechanism is an ordidary longitudinal folder, the angle-bars of whichare indicated at 111 and 112.

The machine which has been. so far described produces a four-pagepaper.- If a product having more pages is desired, the machine may beconstructed as shown in Figs. 4 and 5. The machine illustrated in thesefigures practically consists of two machines, such as have been beforedescribed, placed back to back. Each machine is or may be provided withits own web-supply and a complete set of feeding and controllingdevices. In the construction shown the web from one of the machines ismarked A and the web from the other machine is marked B. The web I3 inthe present machine after leaving the constantly-running feeding-outroll 82 of the feeding-out mechanism passes over suitable guides 113 111 and meets the web A at any suitable point-as, for instance, at theconstantly-running feeding-out roll 82 of the feeding-out mechanismbelonging to the machine which operates on the web A. The two webs aretherefore associated at this point and pass together over thelongitudinal folder, an eight-page paper being thus produced. Byproviding each of these machines with a delivery mechanism they can berun independently, if desired, and in Fig. 4 a second delivery mechanismis indicated in dotted lines for the second machine.

The machine which has just been described is capacitated to print asingle web in two colors on each side. When it is desired to produce aweb thus printed in colors, the weblead will be that indicated in Fig.12. In this figure the web A after leaving the guide 102 of the firstcylinder 6 passes directly to the guide 101 of the second cylinder 6,the web turning and transferring mechanism of the first machine beingcut out. After passing between the second cylinder 6 and its set offorms -11 the Web passes through the web transferring and reversingmechanism of the second machine. From this transferring and reversingmechanism it passes over the guide 102 of the second machine and betweenits impression-cylinder and the set of forms 5. It then passes over theguide 101 of the second machine, the guide 102 of the first machine,between the cylinder 6 of the first machine and its second set of forms5, and then into that web-controlling mechanism of the first machinewhich cooperates with the feeding-out mechanism. With this arrangementof the web-lead, therefore, the web-transferring mechanism of the firstmachine and the feeding and controlling mechanisms of the second machineare not used.

It is to be understood that the invention is not to be limited to thespecific details of construction shown and described in the foregoingspecification.
